Zusammenfassung: | To provide a control circuit, a receiving device, and a control method that controls an external device using a headphone terminal.SOLUTION: A control circuit according to an embodiment includes: detection signal receiving means that receives a detection signal output by a headphone terminal when a plug of a headphone or a plug of an external device having a different impedance from the headphone is inserted into the headphone terminal to which the plug of the headphone for inputting a headphone signal which is a voice signal of a voice content can be connected; headphone signal receiving means that receives the headphone signal; connection determination means that determines whether the headphone or the external device is connected to the headphone terminal on the basis of the detection signal; and decision means that decides whether an output signal is the headphone signal or a signal different from the headphone signal on the basis of the determination.SELECTED DRAWING: Figure 2
【課題】ヘッドホン端子を利用して外部装置を制御する制御回路、受信装置および制御方法を提供する。【解決手段】一実施形態に係る制御回路は、音声コンテンツの音声信号であるヘッドホン信号を入力するためのヘッドホンのプラグを接続できるヘッドホン端子に前記ヘッドホンのプラグまたは前記ヘッドホンとインピーダンスの異なる外部装置のプラグが挿入されると前記ヘッドホン端子が出力する検出信号を受信する検出信号受信手段と、ヘッドホン信号を受信するヘッドホン信号受信手段と、前記検出信号に基づいて、前記ヘッドホン端子に前記ヘッドホンが接続されたのか前記外部装置が接続されたのかを判断する接続判断手段と、前記判断に基づいて、前記出力信号を前記ヘッドホン信号とするかまたは前記ヘッドホン信号と異なる信号とするかを決定する決定手段とを具備する。【選択図】図2 |
